The lightweight durability of the PowerDyne Thrust Nylon plate and the Speed Groove built-in to the Sonar Flat Out wheels combine to create a seriously fast base for the Riedell Vixen skate. To harness this speed, we have equipped the Riedell Vixen with the Riedell 165 boot that comes with a Velcro cinch strap that securely locks your foot in place. With speed and control, the Riedell Vixen has its sights set on the front of the pack.
